playback quotes its arguments.
The quote-quote operator '@w' defeats quotation.
playback always returns done.
playback () (with no arguments) displays all input, output, and intermediate expressions
generated so far.
An output expression is displayed even if it was suppressed by the $ terminator
when it was originally computed.
playback (n) displays the most recent n expressions.
Each input, output, and intermediate expression counts as one.
playback ([m, n]) displays input, output, and intermediate expressions
with numbers from m through n, inclusive.
playback ([m]) is equivalent to playback ([m, m]);
this usually prints one pair of input and output expressions.
playback (input) displays all input expressions generated so far.
playback (slow) pauses between expressions
and waits for the user to press enter.
This behavior is similar to demo.
playback (slow) is useful in conjunction with save or stringout
when creating a secondary-storage file in order to pick out useful expressions.
playback (time) displays the computation time for each expression.
playback (grind) displays input expressions
in the same format as the grind function.
Output expressions are not affected by the grind option.

Arguments may be combined, e.g.,
playback ([5, 10], grind, time, slow).
